Application filed April 26, 1905. Serial No. 258,134.

`To all whom, t may concern:

Be it known that we, GEORGE M. KEPNER and GYRUs M. SMITH, citizens ofthe United States, residing at Fort Dodge, in the county of Webster andState of Iowa, have invented a new and useful Road Grader and Excavator,of which the following is a specification.

Our object is to provide a road grader and excavator adapted to loosenground as it is advanced and to elevate the loose ground into a wagon ordeposit it at its side, as required, in moving ground from the ditchesand sides of the road toward its center.

A further object is to provide means for reversing the movement of anendless carrier, as required, to deliver the loose and elevated groundto either side of the machine and line of advance at the pleasure of theoperator.

A further object is to diminish the friction of the means employed forelevating the loose groundand to reduce the maximum of power heretoforerequired for loosening and elevating ground.

Our invention consists in the construction, arrangement, and combinationof operative elements and subcombinations with a tractable carriage, ashereinafter setforth, pointed out in our claims, and illustrated in theaccompanying drawings, in which- Figure 1 is a top view, and Fig. 2 aside elevation, of the machine that show the positions of all theoperative parts relative to each other and the tractable carriage. .Fig3 is a sectional view of a segment of the wheel that elevates theground. Fig. 4 is a detail view of mechanism for reversing the movementof the side delivery endless' carrier. Fig. 5 is a transverse section ofthe elevatingwheel that takes up loose ground and delivers it on theside-delivery endless carrier.

The numeral 10 designates an oblong frame of a four-wheeled carriagethat must be long enough to allow a large wheel 12 to be placed withinthe frame to rest upon the ground and its upper half to extend above theframe, as shown in Fig. 1. A roller 13 is journaled to the parallelsides of the frame and in rear of the wheel 12 in such a manner thatwhen the carriage is advanced the roller will press against the wheeland impart a rolling motion to the wheel. Rollers 14 on bearers 15,fixed to the parallel side of the frame 1U, as shown in Fig. 2, or inany suitable way, engage the flanges 16 at the edges of the wheel 12 tokeep it parallel with the frame and the line of advance when the machineis in operation. To the flanges 16 are pivoted a plurality of deflectors17, that will be retained stationary, as required, to retain groundthrown between the flanges 16 by a plow to be carried up to the topportion of the wheel and then dumped upon an endless carrier thatextends horizontally through the wheel. Stops 18 are fixed in the wheelto project inward to engage the defiectors 17, as required, to keep themstationary relative to the wheel as they are carried upward as the wheelrolls forward.

A frame 19 is fixed to one of the sides of the carriage-frame, and aplow 2O and a wheelcolter 21, fixed to the frame in any suitable way, asrequired, for loosening ground when the machine is advanced.

Frames 22 and 23 are fixed to the parallel sides and central portion ofthe carriageframe to extend upward and downward, and frames 24 and 25are fixed to their outsides to project horizontally, and rollers 26 and27 journaled to their outer ends to support an endless carrier 28,lmounted on said rollers.

An auxiliary frame 29 for supporting gearing and reversing mechanism isfixed to the carriage-frame 10 in parallel position with the frame 24,and a shaft 30, mounted thereon, and a sprocket-wheel 31, fixed theretoand connected with a sprocket-wheel 32, fixed on the rear carriage-axle,and the two sprocketwheels are connected by a chain as re-v quired, toimpart motion from the axle to the shaft 30. A shaft 34 is mounted inthe frame 24 and has a fixed bevel gear-wheel 35 in alinement withcorresponding wheels 36 on the ends of the rollers 26 and 27, and achain 37 connects the three sprockets, as required, to simultaneouslyimpart motion to the two rollers 26 and 27 and the shaft 34.

Bevel gear-wheels 38 and 39 are fixed on a sleeve 40 on the shaft 30,and a lever 41, conneeted with the sleeve, as shown in Fig. 4, or in anysuitable way to facilitate moving the sleeve, as required, for reversingthe motion of the chain 37 and endless carrier 28.

A roller 42 is mounted in the lower rear corners of the frames 22 and 23to engage the periphery of the large elevator-wheel 12, as required, t0aid in rolling the wheel forward as the carriage is advanced.

A pole 43 is connected with the front carriage-axle for bitching horsesthereto, and a drivers seat 44 andfoot-rest 45 are fixed on the frontend of the carriage-frame 10.

IIO

Braces 46 are fixed to the sides and end portions of the frame 10 andthe frames 22 and 23.

Having thus set forth the purposes of our invention and theconstruction, function, and arrangement and combination of all theparts, the practical operation and utility of the machine will beobvious to persons familiar with the art to which it pertains.

What we claim as new, and desire to secure by Lettefs Patent, isH

l. In a road-grader, a carriage-frame upon vfour wheels and a wheel forelevating ground placed loosely within the frame to roll upon the groundand to elevate loose ground as the carriage is advanced.

2. In a road-grader, a carriage-frame upon four wheels and a wheel forelevating ground placed within the frame to roll upon the ground and toelevate loose ground as the carriage is advanced and a plow connectedwith the carriage-frame for loosening ground.
